What is kept, and where

• Your progress (steps, answers' results, review dates) is stored in your browser only, in IndexedDB. It is never sent anywhere. You can export it, import it, or clear it on the progress page.
• Page views are counted with Cloudflare Web Analytics, to see which pages and lessons are used. It sets no cookies and stores nothing in your browser, and it doesn't follow you across sites. Each count holds the page, the site that linked to it, the kind of browser and device, the country, and how fast the page loaded. Your progress is never part of it. Cloudflare's own privacy policy covers how it handles that data.
• Other sites: the analytics script comes from Cloudflare (static.cloudflareinsights.com); fonts and everything else are served from this site.
• Children: the page-view counts are the same for every visitor and identify no one, at any age.
